MARKING AN SHADING PEN.

SPECIFICATION forming part of Letters Patent NO. 299,045, dated May 20, 1884:.

(No model.)

To all whom it may concern:

Be it known that I, ELBERT E. ALDERMAN, of Portville, in the county of Oattaraugus and State of New York, have invented certain new and useful Improvements in Marking and Shading Pens, of which the following is a full, clear, and exact description.

My invention consists in a fountain rubber marking or shading pen constructed substantially as hereinafter described.

Reference is to be had to the accompanying drawings, forming apart of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 represents a view in perspective of a shadingpen embodying my invention as held by the hand and in the act of being used. Fig. 2 is a partly sectional longitudinal View of said pen, upon a larger scale. Fig. 3 is a section upon the line 00 0c in Fig. 2, and Fig. 4 an inverted or lower end view oft-he rubber portion of the pen. I

A is the socket or fountain portion of the pen, which may be made of metal and be of circular form in its transverse section, and in the upper end of which is fitted a suitable manipulating stick or holder, D.

B is the shadingpiece or working-end portion of the pen, made of india-rubber, and fitting at its inner end within the lower portion of the socket A, beyond which it projects at its outer end any desired length or distance, and is made beveling on opposite sides, or wedge-shaped, as at s 8, toward its outer extremit'y, terminating in a flat or straight blunt edge, the side ends of which may be sloped or rounded off when the pen is purely or mainly a marking one, as shown by dotted lines a a in Fig. 2. The upper or inner portion of the rubber B may be of square or other suitable form in its transverse section, so that when fitted within the lower portion of the socket A it will leave side channels or spaces .for flowof the shading or marking fluid, and said rubber piece B has also feeding-grooves b 2) down or along it to nearly its point or working-edge. It may be secured within the socket A, either by a pin, C, or by teats made by inv denting the socket from the outside, or by both. A vacant space is left in the handle or socket A, between the top of the rubber B and the inner end of the stick D, to form a reservoir, m, for the ink or fluid being used, in which portion of the socket one or more airholes, a a, are or may be made."

Before using the pen it is dipped in the ink or fluid which charges the reservoir in the socket. By suitably holding or turning the pen in the hand it will make marks of any required or different widths, and do either coarse or fine shading. Being less flexible, it may be used much easier than a brush, and a steady feed as needed of the fluid will be kept up down the sides of the rubber or side grooves, b b, therein, and the pen, by reason of its reservoir, will hold a very much larger supply of ink or fluid than a brush. It will make a smoother mark, too, thanabrush, and make marks of very much greater varying width than a steel pen, while it may be used with almost or quite as much freedom as a leadpencil, though, of course, doing coarser work.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a fountain rubber marking or shading pen, the rubber piece or working-end portion B, of wedge shape at its lower end, as described, and provided with exterior feedinggrooves, 1), down its sides, essentially as described.

2. In a fountain rubber marking or shading pen, the combination of the socket A, constructed to form a supply chamber or reservoir, with the rubber piece or working-end portion B of the pen, provided with externally-arranged feeding grooves b, substantially as specified.

3. In a fountain rubber marking or shading pen, the combination, with the socket A, constructed to form a supply chamber or reser.- voir, of the rubber piece or working-end portionB of the pen, constructed to leave channels or spaces between it and the portion of the socket within which it fits, essentially as and for the purpose herein set forth.

ELBERT E. ALDERMAN.
